Investigations On Film Cooling At Hypersonic Mach Number Using Forward Facing Injection From Micro-Jet Array
(2010-07-16)A body in a hypersonic flow field will experience very high heating especially during re-entry. Conventionally this problem is tackled to some extent by the use of large angle blunt cones. At the cost of increased drag, ... -
Investigations On High Rayleigh Number Turbulent Free Convection
(Indian Institute of Science, 2005-08-31)High Rayleigh number(Ra) turbulent free convection has many unresolved issues related to the phenomenology behind the flux scaling, the presence of a mean wind and its effects, exponential probability distribution ... -
Investigations on Impinging Shock Wave and Boundary Layer Interactions in Hypersonic Flow
Shock boundary layer interactions (SBLIs) rank among the most fundamental problems in high-speed aerodynamics and are a primary concern in hypersonic flows. Shocks at hypersonic speeds are typically strong enough to separate ... -
Investigations on Miniature Loop Heat Pipe with Flat Evaporator
The present investigation on a miniature loop heat pipe (LHP) with flat evaporator is motivated by two factors. Firstly, miniature loop heat pipes are required for thermal management of small electronics in spacecraft with ... -
